flight control tower

Try checking out this first. Bought one last year and couldn't be more happy with it. You can still keep your original ski pylon.

I have a 69 Correct Craft Southwind with a tower. These old boats are more then capable of handling the pressure of wakeboarding. Have fun, play safe.

I have used my 1977 martinique (see diaries) all last year with no problems whatsoever. There is only like maybe 200 pounds of force on the wakeboard rope. The fiberglass area where I mounted the tower is pretty thick. If you are going to wakeboard, you need a tower, so start building! I got the fittings online, just do a search for Kee-Klamp fittings. You have to match them with the corresponding pipe size. They are about 8$ a piece and they save tremendously on fabrication.

I would advise against adding a tower to your martinque.The towers on the newer boats have structurally reinforced mounting points to enable the tremendous forces to be distributed equally along the deck surface.Your boat was designed as a pleasure/ski boat,not a wakeboard tower boat,don't risk the serious damage or injury possibility.
